This is the Illinois EPA's 12th Annual Report. It describes the management of nonhazardous municipal solid waste by the state's solid waste landfills and transfer stations. The report is divided into sections representing Illinois EPA. Each regional section includes newly designed specification pages describing the chief physical characteristics of each landfill; its location and hours of operation; tipping fee; quantities of wastes received (in gate cubic yards, tons, and tons per day) for the last three years; the landfill's certified remaining capacity (in gate cubic yards and tons) for the last two reporting dates; solid waste management fees paid in 1998; which Agency regional field office or delegated local authority inspects the facility; and the name, address, and phone number of the landfill's owner and operator. Similar but scaled down specification pages are included for each transfer station. In all, this report includes details of 68 landfills, 79 transfer stations and 53 compost facilities.
